Minimally invasive and less invasive procedure is becoming more and more common in
medical therapy. Image guidance is an indispensable component in minimally invasive …

In this review, we discuss state-of-the-art developments in 3D models for small and rigid
structures. This includes the pros and cons of cutting-edge range cameras used as active 3D …

There is clinical evidence that suppressing the bone structures in Chest X-rays (CXRs)
improves diagnostic value, either for radiologists or computer-aided diagnosis. However …

In the context of retinal microsurgery, visual tracking of instruments is a key component of
robotics assistance. The difficulty of the task and major reason why most existing strategies …

Real-time visual tracking of a surgical instrument holds great potential for improving the
outcome of retinal microsurgery by enabling new possibilities for computer-aided techniques …

Automatic visual detection of instruments in minimally invasive surgery (MIS) can
significantly augment the procedure experience for operating clinicians. In this paper, we …

The goal of this paper is to introduce a direct visual tracking method based on an image
similarity measure called the sum of conditional variance (SCV). The SCV was originally …

Retinal Microsurgery (RM) is performed with small surgical tools which are observed
through a microscope. Real-time estimation of the tool's pose enables the application of …

Purpose Recovering tissue deformation during robotic-assisted minimally invasive surgery
procedures is important for providing intra-operative guidance, enabling in vivo imaging …

Free-form surface matching that aligns measured points with a design model is a common
problem in manufacturing automation. In this paper, an iterative variance-minimization …
